Ceramic coating is a chemical polymer solution that is placed to the exterior of a car to protect it against external paint damage. It’s usually applied by hand and mixes in with your car’s paint, adding an extra layer of hydrophobic protection. The factory paint job on the car is unaffected by this chemical bonding and formation of a new layer. While many vehicle enthusiasts and even detailers believe ceramic coating is a substitute for clear bra (paint protection film), it is actually a substitute for waxing. The major goal is to keep dirt, water spots, filth, and stain marks off the paint job, which would harm the clear coat.
